To be honest, our scroller works phenomenally and performs fantastic. Not being a marketing guy with those words but it really performs like any native app. That being said, we always have our eye on how to do things better so I can't rule out that we will never look into it.

I was wondering if anyone had made any progress on this? I've tried subclassing Ext.Container and modifying the CSS to enable native scrolling for the container's content. I can get it to work on Chrome and Safari but not on iOS.

I've tested the native scrolling (in a simple static HTML file) with a huge grid of images (over 200 images ~15kb each) and the performance is perfect on my iPhone 4. The same layout with only 25 images using Sencha's scrolling is extremely choppy.

I've tried the following CSS on the container's "x-inner" element, but to no avail:

+1 to the above this question.
p.s: native scrollbar works very very fast and, smooth, without any lags with 16 000 DOM elements on my ipod touch, sencha's one starts lagging after 400-500 elements in DOM
